IIIVIIPROVEM ENT IN CAR-WIN oows.

Specification forming part of Letters Patent N 0. 222,518, dated December 9, 1879 application filed I September 29, 1879.

Tooll whom it may concern:

Be it known that 1, WILLIAM W. MAOKALL,

Jr., of Savannah, in the county of Ohatham and State of Georgia, have invented a new and valuable Improvement in Oar-Windows; and I do hereby declare that the following is a full, clear, and exact description of the con-' struotion and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked'thereon.

Figure l of the drawings is a representation of a perspective view of my improved ventilating car-window. Fig. 2 is a perspective view of the upper part thereof, and Fig. 3 is a like view of the lower part of the same.

This invention has relation to improvements in devices for ventilating-a car by means of its windows, and the nature of the invention consists in combining with a vertically-sliding main sash-frame, arranged in the windowframe in the side of the car, and provided with a vertical center bar, of supplementary sashframes hinged to saidcenter bar and opening oppositely, and angular metallic plates at the top and bottom of said hinged sashes, to exelude rain and snow, smoke or cinders, as will be hereinafter more fullyset forth.

In the annexed drawings, the letter A designates a window-frame arranged in the side sashes O O. f These sashes, when closed, are flush with the slide-sash, and offer no obstaole to its being raised or lowered; At the bottom of each of these sashes G O is a metallic plate, D, secured to the outside of the car, and

having an angular horizontal extension, 0, provided on its outer edge with a stop-flange, 0. These extensions taper to a point at the joint of the center bar and sashes, and when the latter are open their lower edges rest upon them and bear against the stop-flange c, as shown in Fig. 3.

At the top of sashes O C are secured, to the outside of the car above the window-frame, the angular metallic water-shed plates G, which bend outwardly when the sashes O are opened,

and are held in close'contact therewith by means of a spring, S, secured at one end to the car above the said plates, and hearing at the other end against the same. I may, however, construct them like plates D, if I so elect.

Sometimes the angular plates D may be hinged to the main sash, as shown in Fig. 1, and, when the sashes (J G are opened, are thrown down, thus closing the interval between the said sashes and the main sash-frame B. The plates G close thelike interval at the tops of sashes C O and exclude rain, dust, and cinders, as well as smoke.

In going in a given direction the sashes G farthest from the front end of the car only are opened, the others remaining closed, and an eddy or exhaust action is produced at the opening of the window, that speedily withdraws from the car foul air and gases.

What I claim as new, and desire to secure by Letters Patent, is-

In a car-ventilator, the combination, with a vertically-slidin g main sash-frame, B, having the vertical center bar, I), and the oppositelyopening supplementary sashes O G, hinged to said center bar, of the angular metallic plates G D, respectively, at the tops and bottoms of said sashes, and closing the intervals between them and sash B, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.
